Description:

MAJOR LVGL UPDATE to v9.0.0

Changes to the C interface are described here: https://docs.lvgl.io/master/CHANGELOG.html

It should be minor changes since we provide synonyms for all functions that changed names.

HASPmota is supposed to have no changes.

Improvements:

• Freetype upgraded to 2.13.2, and now supports BDF (bitmap) fonts embedded in TTF

Known issues:

• PNG decoding might fail on non-PSRAM due to change of cache behavior, see Regression in v9, lodepng fails if cache is too small lvgl/lvgl#5579

Mhh, performance loss in V9. Reason unclear.
lvgl/lvgl#5459

[s-hadinger]

The performance impact was not obvious in my test. In Tasmota the biggest performance hit comes from the fact that we don't fully use DMA because of SPI conflicts with other devices

I'll merge to see if our users also notice performance issues.

I just created the following issue:
#20717
Might it be related to this PR?

[s-hadinger]

I doubt since you only use Display commands
